Question

I’m using SQLite. I have two tables:

Log:
    pid INTEGER PRIMARY KEY AUTOINCREMENT
    action INTEGER NOT NULL
    .... ect.

ErrorExtras:
    pid INTEGER REFERENCES log(pid)
    msg TEXT,
    request TEXT

Now when an error occurs, I want to insert into both. Inserting into Log is easy, as it generates the PID, however, inserting into ErrorExtras is harder since I don’t know the PID without doing a query. If I insert into Log, query for the PID and then insert into ErrorExtras, that seems quie messy. Is there some kind of shortcut for these kinds of inserts?

In my case, this is possible because the other info in log uniquely identifies the pid (so there’s a combined key), but what if this weren’t the case?

Answer 1

You needn’t query for the insert_id, just use the last_insert_id in the select statement in ErrorExtras and Bob’s your uncle.
